DESC: The Accutune Digital Tuner is a high performance hybrid tuner capable of receiving both digital and analog broadcasts. It uses a signal processor to effectively control noise and distortion, and its proprietary matching circuits allow it to transform and separate digital or analog signals. When digital broadcast signals drop out, generally the picture either disappears or becomes filled with block-noise, but the Accutune Digital Tuner produces a beautiful picture even under difficult reception conditions, such as when there are obstacles interfering with direct signal access. This DVD recorder offers twice the horizontal resolution (500 lines vs. the 250-line standard) of many other DVD recorders when recording in LP mode. What does this mean? It means you can fit up to four hours of recordings on one DVD (4.7GB capacity) and still enjoy the crisp, vibrant and exceptionally detailed images delivered by 500 lines of horizontal resolution.
